Summary:The Mundwara alkaline complex is a multiple intrusive body consisting of rocks ranging in composition from ultrabasic to foidal syenites and carbonatites emplaced in Erinpura granites. The multivariate statistical technique of clustering has been applied to the suite to delineate the various intrusive and extrusive phases. Major-element clustering confirms the internal consistency of the groups defined on the basis of petrography and chemistry. Syenites appear to belong to two different phases. From the trace element clustering, the trachybasalt dykes are considered to belong to more than one phase of intrusion. REE clustering separates the ol-hy normative and ne-normative rocks into two separate clusters, raising a doubt about common parentage for these two types of rocks. [V.K.N.]
